Abstract
Restoration of audio information embodied on a soundtrack of a motion picture film advantageously occurs by scanning the film with a beam of light to capture the image in the form of a digital signal via an imager. The digital signal undergoes storage in a storage mechanism (300) and subsequent processing via controller. The controller applies one or more statistical processing algorithms to eliminate deficiencies and to enhance the quality of the audio embodied in the soundtrack.
Claims26
A method for restoring audio information embodied within an analog, optically-recorded variable density soundtrack of a film, comprising the steps of:
- optically scanning the soundtrack to yield a digital signal representation of the audio information;
- storing the digital signal;
- applying at least one statistical processing technique to the stored digital signal to restore at least one characteristic of the audio information.
A system for restoring audio information embodied within an analog optically recorded variable density soundtrack of a film, comprising the steps of:
- a optical scanner for scanning the soundtrack to yield a digital signal representation of the audio information;
- a storage system for storing the digital signal;
- a processor for applying at least one statistical processing technique to the stored digital signal to restore at least one characteristic of the audio information.
